TP-Link Omada ER706WP-4G 4G router, dual SIM, Wi-Fi 6, 4 × PoE+

The ER706WP-4G has two nanoSIM slots. According to the manufacturer, dual SIM is meant for automatic failover and backup WAN: if one mobile or wired connection fails, the other takes over, and the till, cameras and office computers stay online. Supported 4G bands are 800, 850, 900, 1500, 1700, 1800, 1900, 2000, 2300, 2400, 2500, 2600, 3400, 3500, 3600 and 3700 MHz. As a further option, a 3G/4G USB modem can be plugged into the USB port.

Dual-band Wi-Fi 6 with OFDMA and MU-MIMO serves several devices at once, so a small office or café does not always need a separate access point. Five detachable external antennas with gain of up to 4.5 dBi concentrate the signal. Four gigabit ports supply PoE+ power, so an access point, IP camera or IP phone can be connected with a single cable and no separate power adapter.

The router supports IPsec, PPTP, L2TP, OpenVPN and WireGuard tunnels, up to 50 at the same time. That lets you link a branch to the head office or give remote employees secure access to the internal network. VPN passthrough also lets devices' own VPN connections through. The wired WAN port supports DHCP, PPPoE, L2TP and PPTP connections, so the router works with different internet providers.

The ER706WP-4G is part of the Omada SDN system: Omada gateways, switches and access points can be managed centrally through the cloud controller or the Omada app, including across several sites. Without the cloud, management runs in the web interface. SSID-based VLANs separate, for example, guest and staff Wi-Fi, and SNMP, SNMPv2, SNMPv3 lets network monitoring tools watch the device.

The router offers URL filtering and traffic filters, and Wi-Fi encryption supports WPA, WPA2 and WPA3-Personal. The black case measures 226 × 131 × 35 mm and sits on a desk or mounts on a wall, with indicators for power, system, status, LTE and WLAN. The manufacturer lists an operating temperature of 0–40 °C, and power comes from a DC adapter.

Small businesses, tills, cafés and site offices where the internet has to keep working when one connection is lost; companies already running Omada switches and access points; and IT administrators who want a 4G backup line, Wi-Fi 6, PoE+ ports and VPN in one device.
